VueJS process component or HTML using a function - vue.js

Question

I understand how this works from the VueJS Documentation:
<div id="components-demo">
<button-counter></button-counter>
</div>
And also this:
<div id="app">
<a v-on:click="loadElement(request, etc)">Load</a>
</div>
Is there any way to write the equivalent from a function and have Vue pick it up? For example as this:
<div id="app">
{{ writeComponent('component-name', etc) }}
or
{{ writeElement('loadElement') }} <!-- which then writes the component above -->
</div>
The reason for this is that in this context quite a few components might need to be written and writing it out in HTML would be cumbersome.

You could use the render function like below:
Vue.component('button-counter', {
template: '<span class="bc">bc</span>'
})
new Vue({
el: '#app',
data: {
request: 'req!',
etc: 'etc!',
buttonCounters: []
},
methods: {
loadElement(r, e) {
console.log('loadElement', r, e);
this.buttonCounters.push(r);
}
},
render(h) {
let bcs = this.buttonCounters.map(bc => h('button-counter'));
let loadLink = h('a', {on: {"click": ($event) => { this.loadElement(this.request, this.etc)}}}, ["Load"]);
return h('div', {attrs: {"id": "app"}}, [loadLink, " ", ...bcs])
}
})
<script src="https://unpkg.com/vue"></script>
<div id="app"></div>
Though the same can be achieved via regular template and v-for:
Vue.component('button-counter', {
template: '<span class="bc">bc</span>'
})
new Vue({
el: '#app',
data: {
request: 'req!',
etc: 'etc!',
buttonCounters: []
},
methods: {
loadElement(r, e) {
console.log('loadElement', r, e);
this.buttonCounters.push(r);
}
}
})
<script src="https://unpkg.com/vue"></script>
<div id="app">
<a v-on:click="loadElement(request, etc)">Load</a>
<button-counter v-for="(bc, index) in buttonCounters" :key="index"></button-counter>
</div>
